JavaScript Sleep : In JavaScript, the sleep() function is not a built-in function. However, you can achieve a similar effect by using the setTimeout(), setInterval() or Date.now() functions.
function sleep(ms) { return new Promise(resolve => setTimeout(resolve, ms)); } console.log('Hello'); sleep(2000).then(() => { console.log('World!'); }); 运行这段代码,你会在控制台看到 “Hello”。然后,在短暂的两秒钟后,“World!”v会接着出现。这是一种既简洁又有效的引入延迟的方法。
除了Narrative JS,jwacs(Javascript With Advanced Continuation Support) 也致力于通过扩展JavaScript语法来避免编写让人头痛的异步调用的回调函数。用jwacs 实现的sleep,代码是这样: function sleep(msec) { var k = function_continuation; setTimeout(function() { resume k <- mesc; }, msec); suspend; } 1...
function sleep(msec) { var k = function_continuation; setTimeout(function() { resume k <- mesc; }, msec); suspend; } 这个语法更吓人了,并且还是java里不被推荐使用的线程方法名。坦白说我倾向于 Narrative JS。 同Narrative JS一样,jwacs也须要预编译,预编译器是用 LISP 语言编写。眼下也是 Alpha...

we are using JavaScript either by web browser or Node.js. We all face a difficult situation in delaying a loop in JavaScript unlike C++ where we have sleep() function, but there is nothing like this in JavaScript. All we have in JavaScript is setTimeout() function, but this is not wha...

用js(javascript)自定一个函数,调用该函数,在页面显示 “你好奥巴马” 1.自定义函数的知识点 5.自定义函数 结构: function fn(){} function 定义函数的关键字 (我们还学过一个 var关键字) fn 函数的名字(名字随意取,但要注意命名规范) () 代表参数集 {} 代表函数体(所有要执行的命令,都在这里写) 调用...
